About Covisn

Covisn is a Hong Kong-based eyewear brand founded on a personal story: after the founder watched a friend lose his job and a colleague's child struggle in school, both because of color blindness, the team set out to make color-correcting eyewear accessible rather than a luxury item. For roughly a decade, Covisn has worked with opticians to design glasses and contact lenses that help people with red-green color vision deficiency see the world with more contrast and clarity. Their core lineup spans indoor glasses, outdoor and sports models, kids' frames, clip-ons, and color-correcting contact lenses. What sets Covisn apart is its focus on affordability without cutting corners on lens technology, paired with a straightforward promise: a full year of warranty coverage and two months to decide if the glasses are right for you.

Customer Experience

Covisn's site is built around a simple path: take the free color blind test, browse glasses by indoor, outdoor, or kids' use, and check out directly. Order tracking, a wishlist, and account management are all available post-purchase. Shipping typically takes 2 days to process plus a handful of business days in transit depending on region, and the FAQ section addresses common concerns in plain language — from how long to wear the glasses to what happens if they don't work for a particular type of color blindness.

Trust & Transparency

Covisn publishes its company details, including its Hong Kong business address and registered name, HK Ideamy Limited, along with a dedicated Trustpilot review page linked from the site. Policies covering shipping, returns, refunds, privacy, and terms of service are all published separately and easy to find. The FAQ is candid that color-correcting eyewear isn't a cure — it manages perception while worn — which sets realistic expectations rather than overselling results.

The People Behind the Product

Covisn's product decisions are shaped by opticians who help customers pick the right lens for their vision type and intended use, rather than a one-size-fits-all frame. The brand has spent years refining its red-green lens filtering technology specifically, rather than treating color blindness as a single, generic problem. Its catalog reflects hands-on iteration — separate lens tints for indoor versus outdoor light, multiple frame styles, and a clip-on option for people who don't want to replace their existing glasses.

On the credibility side, Covisn is transparent about its limitations: its FAQ explicitly states glasses do not cure color blindness and that effects vary by individual and by type of deficiency (protan, deutan, and others). It backs this honesty with tangible guarantees — free returns for 60 days and a full year of warranty — which gives customers a low-risk way to judge results for themselves rather than relying on marketing claims alone.

Best For / Strengths / Limitations / Use Cases

Best for: People newly exploring color-correcting eyewear who want an affordable entry point, parents of color-blind children, and anyone wanting separate indoor and outdoor options.

Strengths: Wide range of frame styles, contact lens alternative, generous return window, worldwide shipping, clear educational content (blog and FAQ) around color blindness itself.

Limitations: As with all color-correcting eyewear, results vary by individual and type of color blindness; the glasses manage perception rather than cure the underlying condition, and effectiveness for less common types (e.g., blue-yellow) may be more limited than for red-green.

Use cases: Everyday indoor tasks like reading and screen use, outdoor activities and driving, sports, and situations like distinguishing traffic signals or fall foliage colors.

Frequently Asked Questions

Do color blind glasses actually work? They can noticeably improve how some wearers perceive red and green hues, though results depend on the individual's specific type and severity of color vision deficiency.

Can these glasses cure color blindness? No. They filter certain wavelengths to make some colors easier to distinguish while worn, but color perception returns to normal once the glasses come off.

Are the lenses see-through, or heavily tinted? The indoor styles look close to regular clear glasses, while outdoor and sunglasses styles use tinted lenses for use in daylight.

How long should someone wear them before judging the results? The general guidance is to wear them for at least 10 hours across different situations over one to two weeks to get a fair sense of the effect.

What's the return policy if they don't help? Covisn offers a 60-day risk-free return window, so buyers can test the glasses and send them back if they're not the right fit.

Do they work for driving at night? They can help identify red and green traffic signals from a distance, but they're not recommended as general night-driving glasses since they can slightly reduce overall visibility.

Is shipping really free everywhere? Yes, Covisn offers free shipping on all orders, with delivery times varying by region — typically a week or more depending on destination and shipping speed selected.

Do the glasses come with a case? Yes, a protective case is included with purchase.
